Significance Genome-wide identification of changes in the expression of large intergenic noncoding RNAs (lincRNAs) in a classical model of innate immune cell activation revealed a panel of 159 lincRNAs that were highly modulated in stimulated THP1 macrophages. One of the lincRNAs, named TNFα and heterogenous nuclear ribonucleoprotein L (hnRNPL) related immunoregulatory LincRNA (THRIL), was essential for induction of TNFα, functions through a ribonucleoprotein (RNP) complex with hnRNPL, and plays an important role as regulator of physiological and pathological inflammatory immune responses.

The long noncoding RNA THRIL regulates TNFα expression through its interaction with hnRNPL
